Correction of recording power is appropriately performed to an optical disk. The recording power correction method includes a step of temporarily stopping data recording into an optical disk, reproducing a result of the relevant data recording, and specifying a detection pattern including a predetermined code in a reproduction signal; a step of detecting a signal state in the reproduction signal corresponding to the detection pattern; and a determination step of determining at least a correction direction of recording power in the data recording based on the detected signal state and a reference state specified from the detection pattern. Processing is performed on the basis of the detection pattern in this way, thereby the method can cope with even a recording and reproduction system for optical disk employing the PRML signal processing method.
